Can Social Functioning in Schizophrenia Be Improved through Targeted Social Cognitive Intervention?

Efforts to use cognitive remediation in psychosocial intervention for schizophrenia have increasingly incorporated social cognition as a treatment target. A distinction can be made in this work between “broad-based” interventions, which integrate social cognitive training within a multicomponent suite of intervention techniques and “targeted” interventions; which aim to enhance social cognition alone. Targeted interventions have the potential advantage of being more efficient than broad-based interventions; however, they also face difficult challenges. In particular, targeted interventions may be less likely to achieve maintenance and generalization of gains made in treatment. A novel potential solution to this problem is described which draws on the social psychological literature on social cognition

Facilitating Recovery of Daily Functioning in People With a Severe Mental Illness Who Need Longer-Term Intensive Psychiatric Services:Results From a Cluster Randomized Controlled Trial on Cognitive Adaptation Training Delivered by Nurses

Background: Feasible and effective interventions to improve daily functioning in people with a severe mental illness (SMI), such as schizophrenia, in need of longer-term rehabilitation are scarce. Aims: We assessed the effectiveness of Cognitive Adaptation Training (CAT), a compensatory intervention to improve daily functioning, modified into a nursing intervention. Method: In this cluster randomized controlled trial, 12 nursing teams were randomized to CAT in addition to treatment as usual (CAT; n = 42) or TAU (n = 47). Daily functioning (primary outcome) was assessed every 3 months for 1 year. Additional follow-up assessments were performed for the CAT group in the second year. Secondary outcomes were assessed every 6 months. Data were analyzed using multilevel modeling. Results: CAT participants improved significantly on daily functioning, executive functioning, and visual attention after 12 months compared to TAU. Improvements were maintained after 24 months. Improved executive functioning was related to improved daily functioning. Other secondary outcomes (quality of life, empowerment, negative symptoms) showed no significant effects. Conclusions: As a nursing intervention, CAT leads to maintained improvements in daily functioning, and may improve executive functioning and visual attention in people with SMI in need of longer-term intensive psychiatric care. Given the paucity of evidence-based interventions in this population, CAT can become a valuable addition to recovery-oriented care

Effectiveness and cost-effectiveness of cognitive adaptation training as a nursing intervention in long-term residential patients with severe mental illness:study protocol for a randomized controlled trial

Background. Despite the well-known importance of cognitive deficits for everyday functioning in patients with severe mental illness (SMI), evidence-based interventions directed at these problems are especially scarce for SMI patients in long-term clinical facilities. Cognitive adaptation Training (CAT) is a compensatory approach that aims at creating new routines in patients’ living environments through the use of environmental supports. Previous studies on CAT showed that CAT is effective in improving everyday functioning in outpatients with schizophrenia. The aim of this study is to evaluate the effect of CAT as a nursing intervention in SMI patients who reside in long-term clinical facilities. Methods/Design. This is a multicenter cluster randomized controlled trial comparing CAT (intervention group) as a nursing intervention to treatment as usual (control group). The primary goal is to evaluate the effectiveness of CAT on everyday functioning. Secondary outcomes are quality of life, empowerment and apathy. Further, an economic evaluation will be performed. The study has a duration of one year, with four follow-up assessments at 15, 18, 21 and 24 months for the intervention group. Discussion. There is a need for evidence-based interventions that contribute to the improvement of the functional recovery of long-term residential patients. If our hypotheses are confirmed, it may be recommended to include CAT in the guidelines for SMI care and to implement the method in standardized care. Trial registration.

International Assessment of Functional Skills in People with Schizophrenia

Disability is very common in schizophrenia and is related to cognitive impairments, some illness symptoms, and deficits in skills needed to function in the everyday environment (i.g., functional capacity). Research on measurement of the ability to perform the skilled acts required for successful everyday functioning has advanced considerably in the past five years. However, different environmental situations require different skill sets, and one of the major challenges in research on functional capacity is identification of the differences in skills that are required across environments. This article reviews the challenges associated with international measurement of functional capacity. The authors present their perspectives on what can be done with existing measures and what needs to be done in the future. As America becomes more multicultural, these challenges will also occur close to home as well

Performance-based measures of functional skills: usefulness in clinical treatment studies

Recently, attention to the assessment and treatment of functional disability has increased notably. It is widely understood that impairments in everyday living skills, including independent living skills, social functions, vocational functioning, and self-care, are present in people with schizophrenia. It has also become clear recently that assessment of these skills can pose substantial challenges. These challenges include selection of meaningful short-term outcome measures and avoiding bias and reduced validity in the data. Self-report, direct observation, and informant reports of everyday disability all have certain advantages but appear to be inferior to direct assessment of skills with performance-based measures. This review outlines the issues associated with the assessment of functional skills and everyday functioning and provides a description of the strengths and weaknesses of these approaches. We conclude that direct assessment of functional capacity has substantial advantages over other measures and may actually provide a more direct and valid estimate of functional disability than performance on the more distal neuropsychological assessment measures

Cognitive Rehabilitation for Schizophrenia and the Putative Role of Motivation and Expectancies

Cognitive rehabilitation (CR) approaches seek to enhance cognitive processes or to circumvent cognitive impairments in schizophrenia in an effort to improve functional outcome. In this review we examine the research findings on the 8 evidence-based approaches to cognitive remediation listed in the 2005 Training Grid Outlining Best Practices for Recovery and Improved Outcomes for People With Serious Mental Illness, developed by the American Psychological Association Committee for the Advancement of Professional Practice. Though the approaches vary widely in theoretical orientation and methods of intervention, the results are, for the most part, encouraging. Improvements in attention, memory, and executive functioning have been reported. However, many persons with schizophrenia are more impaired in real-world functioning than one would expect given the magnitude of their cognitive deficits. We may need to look beyond cognition to other targets such as motivation to identify the reasons that many persons with schizophrenia demonstrate such marked levels of disability. Although a number of current CR approaches address motivation to varying degrees, treating motivation as a primary target may be needed to maximize CR outcomes

Cognitive functioning in schizophrenia: a consensus statement on its role in the definition and evaluation of effective treatments for the illness

Truly effective treatments for schizophrenia require much more than clinical efficacy. Symptom improvement is all that is required to demonstrate clinical efficacy. However, for a treatment to be effective in a wide-ranging manner, improvement in various life domains, such as social functioning, independent living, and employment, should also be found. Thus, a much wider range of improvements, not widely produced by previous treatments, is required to take treatment for schizophrenia to a new level of effectiveness. A teleconference consensus meeting was held with the bylined authors on December 10, 2002, to explore the factors that hinder the most effective treatments for schizophrenia. We argue that a possible unifying factor underlying these apparently disparate domains of effective treatment is cognitive functioning, which is impaired in people with schizophrenia. Treatment of cognitive dysfunction may have a central role in increasing the breadth of effective treatment for schizophrenia. Novel antipsychotics and specific cognitive-enhancing medications have preliminarily been shown to have cognitive benefits that might lead to broader effectiveness of treatments, eventually reflected in improvements in the daily lives of patients. These treatments may have their greatest impact when combined with focused psychological interventions. While the research to date does not provide a large number of successes, this area will be one of considerable research interest for the next decade, with developments likely to be very important to clinicians treating patients with schizophrenia
